Had a schwaginaw come in the shop; 2.85 1st w. OD. OD will work on any Sag 3spd; but realistically, you want a numerically low 1st gear, to allow for the high axle and not drop your RPMs too low. Say a 3.7 w. the 2.8 1st and the OD. Life would be sweet.

I've been told I can get a RE from a 4x4 Blazer or S10 that will be an easy bolt up without a driveshaft or any other mods. I've found one from a '97. Does anybody know if it's really a simple remove one and bolt up the other swap as I've been told?

OK. Just got home after being on the road all week. Truck was delivered yesterday. Yes I have driven the '52. No I have not driven the '97 Blazer if that's the question. Here's another curve ball. As soon as I got home today I looked under the truck and noticed the drive shaft is not open. There are no visible U-joints. Now it's looking like more work already. I assume that would mean a drive shaft change at the very least. Does that mean a tranny change also? I think it's time to call my mechanic

I wasn't sure if it would be a closed driveshaft considering the tranny change. So yup you'll need to change the tranny too. Unless you find an adaptor to change out the output on the tranny. I've seen them. Don't remember who makes them.
Patrick's might know.
Looks like a rear gear change is in your future.
What I meant by having driven it yet is you might like to leave it alone once you drive it.
